The silkscreen is a marking method for PCBs. It is also called legend print or annotation print. The silkscreen print is applied by means of a screen printing process or by full-surface printing with subsequent printing and development. For the latter, no screen is required, which makes this process suitable for small quantities.
Recently, the process can also be carried out using a special type of printer, which is similar to an inkjet printer. Consequently, even single pieces are relatively cheap to print, since no film is necessary for the exposure.
